can anyone suggest me on how to generate a structured grid for triangle.its very urgent for me

i think you can divide the triangle into block of rectangle,and you can get the structure you need. Just try!

Bharath,

Generate a point or vertex at the centre of a triangle, join this point or vertex with the midpoint of all the three edges or line of a triangle. The way u split it depnds on the meshing software u r using!. After joining, u will find three rectangles within one triangle, so u can now generate a structured mesh for each rectangle.

Hope this helps.
